Synthetic Diamond Manufacturing
Diamond compaction tooling, and the substrates upon which the polycrystalline diamond (PCD) is sintered are proven products manufactured by General Carbide. The extremely high compressive loading, accompanied by fatigue from the cyclical action of the press, requires a homogeneous, pore free microstructure for the compaction anvil. We supply a carbide grade that delivers high-cycle life due to the double hot isostatic pressing (HIP) process the material undergoes. We sinter all of our products in a sinter-HIP furnace, where the simultaneous application of heat and pressure fully consolidate the material's microstructure. Our diamond compaction anvils undergo a separate and additional post-sintering operation. They are then sinter-HIP’d under higher pressure, and at temperatures that almost reach the original sintering temperature. This process ensures that the material will contain no residual voids or flawsand the extra HIP operation adds a higher degree of performance reliability than comparable materials have.
General Carbide is also a major supplier of carbide substrates and backup discs. We press and sinter substrates with intricate surface configurations built into the press tooling. Our superior ultrasonic cleaning operation and proprietary cleaning solution provide a surface finish condition which is receptive to the PCD table without pre-cleaning and makes brazing easier.
